UHW1H471MHD6

The UHW1H471MHD6 is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UHW series. It is a radial-lead, polarized electrolytic with 470 µF capacitance rated at 50 V, designed for general-purpose smoothing and decoupling in electronic power circuits.

Key design strengths include low impedance at higher frequencies, high ripple-current capability, and long endurance (10,000 hours at 105°C), making it suitable for equipment that requires reliable bulk capacitance in a compact can package (φ12.5 × 20 mm, lead spacing 5.0 mm).

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 50 V rated voltage and capacitance tolerance of –20% to +20% (120 Hz, 20°C).
• High Ripple Current — Rated low-frequency ripple current of 1.15 A (120 Hz) and high-frequency ripple current of 2.3 A (10 kHz), supported by frequency coefficients in the UHW series for improved performance across frequencies.
• Low Impedance — Low D.C. impedance (81 mΩ) for effective high-frequency filtering and reduced voltage drop under ripple conditions.
• Long Endurance — Life rating of 10,000 hours at 105°C with specified limits on capacitance change, tan δ, and leakage current after endurance testing.
• Wide Operating Temperature — Operates from –40°C to +105°C, enabling use across broad ambient and thermal environments.
• Compact Radial Package — φ12.5 × 20 mm aluminum can with radial leads and 5.0 mm lead spacing (lead spacing tolerance ±0.5 mm) for through-hole mounting and straightforward board placement. Packaging options include bulk (no terminal forming) and bag packing.
• Low Leakage — Specified leakage current of 235 µA (measured per product conditions), supporting stable idle behavior in circuits.
• RoHS Compliant — Manufactured in compliance with RoHS directives as stated for the UHW series.

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple suppression on DC power rails where 470 µF and 50 V rating are required.
• DC–DC Converter Input/Output — Input and output decoupling for converters that demand high ripple-current handling and low impedance at switching frequencies.
• Industrial and Instrumentation Electronics — Energy storage and local decoupling in control modules and instrumentation operating across –40°C to +105°C.

Unique Advantages

• High ripple-current capability: 1.15 A at 120 Hz and 2.3 A at 10 kHz provide margin for high-frequency switching environments.
• Low impedance for stable performance: 81 mΩ D.C. impedance reduces voltage ripple and improves transient response in power circuits.
• Compact, through-hole form factor: φ12.5 × 20 mm radial can with 5.0 mm lead spacing balances board-space efficiency with easy assembly.
• Long-term reliability: 10,000 hours endurance at 105°C supports deployment in designs requiring sustained thermal and electrical stress tolerance.
• Controlled leakage and tolerance: Specified leakage current (235 µA) and ±20% capacitance tolerance help designers size components for predictable system behavior.
• Regulatory compliance: RoHS compliance for use in products requiring restricted-substance adherence.
